Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 26 points:

(1,2);(3,4)(5,9)(6,7)(8,10)(11,12,15,17)(13,18,14,16)(19,20)(21,24)(22,26)(23,25);(4,7)(8,9)(11,13,15,14)(12,16,17,18)(19,21,23,26)(20,24,25,22);(3,5,6,10)(4,8,7,9)(11,14,15,13)(12,16,17,18)(19,21)(20,22)(23,26)(24,25);(3,4)(5,8)(6,7)(9,10)(11,12)(13,18)(14,16)(15,17)(19,22)(20,21)(23,24)(25,26)
